Abstract: An improved wellhead structure having a housing (12) with an internal landing seat (18) to receive the landing shoulder (20) on a hanger (22) having a bore (30) with a counterbore (32) below the bore and a shoulder (34) therebetween. A hanger mandrel (48,60) positioned within the counterbore (32) and has an external flange (50) having a diameter less than the diameter of the counterbore. A first bushing (54) is positioned above the mandrel flange (50) and in engagement with the shoulder within the hanger counterbore, and a second bushing (56) is positioned within the counterbore below the mandrel flange. A support sleeve (42) is positioned within the hanger in supporting relationship to the second bushing (56). The bushings (54,56) are of an electrical insulating material and sized to retain the mandrel in spaced relationship with respect to the hanger to prevent electrical connection therebetween. This structure also is used for supporting and sealing a tubing string or a section of a tubing string in a well while electrically insulating the section from the remainder of the string.

Abstract: Optical interference structures incorporating porous films. These structures are capable of exhibiting a colour by interference effects caused by the interference of light reflected from various layers within the structure. Basically, the structures comprise a reflective substrate (10), a porous transparent dielectric film (11) on the substrate and at least one semi-transparent layer supported by the porous dielectric film. The structure is such that there are at least two reflective surfaces separated by an optically thin porous layer of the dielectric film. These structures can be formed by several methods, but the most convenient involves the porous anodization of a substrate metal (10) (e.g. aluminum) to form the dielectric film (11) and the deposition of a semi-transparent metal layer (12) within the pores or on the film surface. The structures can be made inexpensively and are capable of generating strong and, if desired, dichroic colours. The porous nature of the film can also be exploited to create colour shifts. The structures can be used for decorative purposes or to create a wide range of indicators, sensors, security devices and the like.

Abstract: An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for automatically monitoring, displaying and recording inflation data when the syringe system is used to inflate the balloon catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member can be released by withdrawing the syringe plunger toward the rear of the barrel. A piezoresistive semiconductor transducer housed on the barrel of the syringe senses positive fluid pressure applied by the syringe. The electric signal output by the transducer is input to a controller where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that positive fluid pressure is applied and the electronic data representing this information is automatically displayed and recorded. The controller is also programmable to permit optional selection and input of various control parameters, such as a maximum positive inflation pressure that is to be applied, maximum duration for applying positive inflation pressure, initialization of the date and time of an inflation procedure and/or retrieving and displaying inflation data previously recorded for any prior inflation of the balloon catheter or other balloon member.

Abstract: A canopy for use with a ventilator slot extending through a window frame has pressure differential responsive flow control means arranged to progressively close the flow passage through the canopy as the pressure differential increases, thus preventing draughts. The canopy has a body (1) with an inlet and an outlet and a bowed wall (21) therebetween. A normally straight baffle strip (26) is attached to the centre of the wall (21) and there are non-aligned apertures (25,28) in the wall and the baffle respectively. When the pressure differential between the inlet and outlet is low, the baffle is well-spaced from the wall but as the pressure differential increases the baffle (26) is bowed progressively towards the wall against the inherent bias of the strip to progressively close the flow path through the apertures. <IMAGE>

Abstract: A system monitors the performance of a communications network and isolates the location of equipment failures therein through analysis of performance error data. The system passively monitors the performance of the network, operating in the background during normal data and/or voice transmission. The head end generates and inserts multiple error codes, one for each remote unit, into the downstream traffic path. Each remote unit extracts and decodes its respective error code to determine whether a downstream error occurred. Each remote unit then calculates a new error code based on the result of the downstream decode and the respective upstream data message. The head end receives the upstream error codes from all the remote units, decodes them, and accumulates the error data from all remote units over a period of time. An error distribution is generated, and an analysis is performed thereon to isolate the location of error causing equipment failures. The information thus obtained can then be used to initiate facility and equipment protection and/or appropriate maintenance procedures. The invention results in an increased quality of transmission with minimal network down time and minimal impact on overall system performance.
